Hi Ravi,

My pleasure.

Yes, you can show alert message on your requirement as below. In that case you have to modify the code as below:

For Client script:

if (g_form.getValue('variable_name') == 'No') {

alert("Show your message here");

return false; }

For Business rule:

if (current.variables.variable_name == 'No') {

gs.addInfoMessage("Show your message here");

current.setAbortAction(true); }

I hope this helps.Please mark correct/helpful based on impact
